Is it safe to walk past?

Yes. The remediation work is being undertaken inside tents to mitigate and protect the community from any unpleasant odours or other emissions (which would otherwise include a combination of ammonia and naphthalene, the same smell as moth balls).

Air and water treatment plants are on site to ensure all emissions from the worksite are safe and cleaned, posing no risk to the environment or community health. This remediation is cleaning up the dangerous wastes from the past, to make the area safe for use in the future.
